Asynchronous decentralized adjustable robust operation for multi-area integrated electricity–gas systems considering wind power uncertainty

Modern energy infrastructure has evolved into an integrated electricity and natural gas systems (IEGS), which often encompasses multiple geographically-diverse areas. This paper focuses on the decentralized adjustable robust operation problem for multi-area IEGS. Existing distributed algorithms usually require synchronization of all area subproblems, is hard to scale could result in under-utilization computation resources due heterogeneity local To address those limitations, this proposes asynchronous alternating direction method multipliers (ADMM) based model structure only requires communications allows each perform updates with information from a subset but not neighbors, where individual areas’ subproblems are solved independently asynchronously. Meanwhile, linear decision rules (LDRs)-based tailored combine automatic generation control (AGC) fully exploit its potential dealing renewable uncertainty. Numerical results illustrate effectiveness proposed method.
